  • Publication number: 20100287603
    Abstract: Techniques for implementing flexible identity issuance systems to allow users to specify one or more evaluation processes to be carried out by the issuance system based on input identity information. These evaluation processes may be specified in any suitable manner to allow an issuance system to carry out any process for generating output identity information for a content consumer. In some embodiments, an evaluation process may be specified to the issuance system as a series of tasks to be carried out, where each task corresponds to a conditions and an action to be taken when the condition is met. In this way, an evaluation process may be simply and easily specified by what operations are to be carried out, rather than how the operations are to be carried out. An issuer may interpret the specification to determine a functional process for carrying out the tasks.

  • Publication number: 20100001833
    Abstract: The claims based identity model provides a model which associates security identities with claims. The model represents information contained in the claims, as well as, captures relationships between the security identities described in the claims. Finally, the data model can be easily translated to the existing .NET environment without breaking the backward compatibility for existing .NET applications.

  • Publication number: 20090158989
    Abstract: A ship designed for use at high speed and heavy seas having a single long and slender hull with a narrow beam and a more or less vertical bow, whereby the front half of the hull has more or less vertical sides, minimal flare in the bow sections and towards the bow an increase in draught at its center line combined with a more or less similar increase of freeboard and whereby the aft end of the hull has a flat or slightly V-shaped bottom with one or more propellers and/or waterjets as propulsion means. In accordance with the invention the bow has a fillet radius of at least 1% of the beam.

  • Publication number: 20090114137
    Abstract: A ship for use at high speed and/or heavy seas having a single long and slender hull, a sharp bow and the aft end of the hull has a flat or slightly V-shaped bottom with at least one aft rudder, and at least one propeller or water jet for propulsion whereby the foreship has a draught that is equal or more than the draught of the aft end. The bow has a control surface that converts the water flow along the forward moving ship into an adjustable lateral force.

  • Publication number: 20080187415
    Abstract: The invention relates to a method for performing a function or an operation involving a material and/or a device, in particular a non-gaseous material such as a biological material or an electronic material subjected to an operation as a scientific investigation, a medical test or a handling during production, under a gaseous atmosphere in an inner chamber. The invention provides a new principle for avoiding contamination by gaseous materials, airborne particles and other contamination to an inner space, such as a workbench or working chamber, from an adjacent surrounding space such as the ambient atmosphere, or emigration of materials such as hazardous medical material, toxic substances or other pollution to the adjacent surrounding space from the inner space. A workbench is obtained fulfilling all the strictest requirements to a clean working chamber.

  • Publication number: 20070125874
    Abstract: An aromatic dispenser/container dispenses a scent or aroma, based on a fluid in the dispenser. The fluid containing the scented aroma is contained within a bottle or jar, typically of some decorative configuration. The fluid need not be flammable and no flame or heat source is required. A top of the bottle or jar has a top or cap member attached to form a closed container for the scented fluid. The cap member is formed of a porous, clay-type material of the type used in forming porcelain articles. The clay material of the cap member is formed during a first firing of the material is known as bisque, or biscuit. The bisque material of the cap member is hardened and more rigid than are original clay material, but is yet still permeable and porous enough to allow the vapors from the fluid in the container to permeate from the bottle through the bisque material and into the nearby region.

  • Patent number: 5730777
    Abstract: A method for performing a function or an operation involving a material, in particular, a non-gaseous material such as a biological material subjected to a scientific investigation, under a gaseous atmosphere in a closed chamber comprising performing the operation in a housing comprising i) first chamber walls defining a first chamber containing a gaseous atmosphere and ii) second chamber walls defining a second chamber substantially enclosing the first chamber, the second chamber containing a gaseous atmosphere between the first and second chamber walls, the operation being performed in the first chamber while a) the partial pressure of the selected gas species or the total gas pressure in the atmosphere of the second chamber is lower than the partial pressure of the selected species of the total gas pressure, respectively, of the gaseous atmosphere in an adjacent outer third chamber or space. The invention also relates to a housing for performing the operation mentioned above.

  • Patent number: 4107845
    Abstract: Adhesive dental restorative composite comprising a suspension of filler fibers in a liquid polyacrylate resin composition wherein the resin has a viscosity of less than 5000 centipoise. The fibers which may be organic or inorganic generally have lengths of 1 to 100 microns and diameters which are from 1/20 to 1/5 of the lengths. An amine accelerator and a peroxide catalyst for the acrylate resin are included in the composite. The fibers comprise from 30% to 70% by weight of the composite.The referred resin formulation comprises from 25% to 90% by weight of a polyethyleneglycol diacrylate and from 10% to 75% by weight of an aromatic or alicyclic polyacrylate compound.An especially preferred composite is one wherein the resin comprises 40 parts triethyleneglycol dimethacrylate to 60 parts bisphenol-A-bis(3-methacrylato-2-hyroxypropyl) ether having suspended therein calcium silicate fibers having an average length of 5.
